Abstract: A method of forming a cast component and a method of forming a casting mold is provided. The method is performed by connecting at least one wax gate component to a ceramic core-shell mold. The ceramic core-shell mold includes at least a filter, a first core portion, a first shell portion, and at least one first cavity between the core portion and the first shell portion. The ceramic core-shell mold may be manufactured using an additive manufacturing process and may include an integrated ceramic filter. At least a portion of the ceramic core-shell mold and the wax gate component is coated with a second ceramic material. The wax gate component is then removed to form a second cavity in fluid communication with the first cavity.

Abstract: A molding apparatus is provided. The molding apparatus includes a first block configured to receive a moldable article therein, a second block positioned a distance from the first block, and a shim including graphite. The shim is positioned between the first block and the second block, wherein the shim gradually disintegrates when heated such that the second block contacts the first block.
